INSTRUCTIONS for source data:

-after each "0":
first number is node number from which link goes to other nodes,
next numbers up to next "0" 
are nodes numbers where links arrive;

-if there is no outgoing link then the node
is omitted from the list

-TO GET titles:
The file lnk_outLeo.dat has Wikipedia Network
(given by outgoing links) only for connected nodes
(i from 1 to 3282257).
If you want the name of the node i you have to check
the line number i+1 of the file "na2ln"
(since the first line of the file is 3282257)
then you obtain a number j (from 1 to 6855098).
The file "titles" has the list of names of all nodes for j.

In few words: from node i of "lnk_outLeo.dat" you obtain j
using "na2ln" and then you read the name from j-th line of "titles"
